Smorygo — Engineering ToolsPersonal platform to help engineers and enthusiasts design simple and complex gear transmissions with live previews and SVG/DXF exports.
Gear generator
Gear generator
Generate a single involute spur gear or a meshing gear pair. Control module, profile shift, backlash, clearance, discretization, and reference geometry, animate the motion, and export SVG/DXF drawings or 3D STEP/STL models.
Single-stage epicyclic gear tools. Solve a three-gear set from any two known gears, or search whole tooth-count ranges for a target ratio. Includes spacing/collision checks, hunting/GCD validation, animation, SVG/DXF drawings, and 3D STEP/STL export.
Two-stage split-ring planetary solver. Starts from a target overall ratio and tooth-count ranges, applies your constraints, finds valid integer solutions, shows the motion, and exports the geometry as SVG/DXF drawings or a full 3D STEP/STL assembly.
Design a wave reducer with intermediate rolling elements. A wave generator drives caged rolling bodies against a rigid outer wheel. Set body count, generator waves, eccentricity, and size; read both kinematic-scheme ratios, animate the motion, and export the outer wheel, generator, cage, and assembly to SVG/DXF or a full 3D STEP/STL model.
